Group by and "Edit in line" - Conflict in SharePoint View

Hi, I have a view with 2 group by and "edit in line". By default, the groups remain collapsed.

When I edit a item with "edit in line" function, the groups (which are expanded) collapse again...

Is this a bug? Is there hotfix?

There is a topic (http://social.msdn.microsoft.com/Forums/en-US/sharepointgeneralprevious/thread/40e55019-cd74-4c13-bd82-c63153cd055f), but without solution.

Thanks

Everton
